CORNELIUS BEAVER, OF SPANGLER, PENNSYLVANIA.

NUT-LOCK.

Specification of Letters Patent.

Application filed September 26, 1911.

Patented Sept. 24, 1912.

Serial No. 651,403.

To all whom it may concern:

Be it known that I, CORNELIUS BEAVER, a citizen of the United States,residing at Spangler, count-y of Cambria, and State of Pennsylvania,have invented certain new and useful Improvements in Nut-Locks, of whichthe following is a specification.

This invention relates to nut locks.

My object is to provide a nut lock particularly adapted for use on railjoints where a plurality of nuts and bolts are employed, embodying newmeans for locking the nuts for the several bolts in such manner thatthey cannot jar loose, but will permit the nuts to be independentlytightened or loosened and the bolts to be removed independent of eachother without disturbing the locking action on the other nuts.

My invention is set forth fully hereinafter and the novel features arerecited in the appended claim.

In the accompanying drawing: Figure 1 is a side elevation; Fig. 2, aplan view;

Fig. 3, a cross-section on line 33, Fig. 1; Fig. 4, a detail of one ofthe spring arms; and Fig. 5, a detail of one of the screw plugs.

The rail ends are shown at 1 and 2. One of the fish plates 3 is ofordinary construction; the other fish plate 4 is of the usualconstruction save that it is provided with an upward extension 5 whichis received in cut-out portions 6 of the respective rails and abuts thewalls of said cut-out portions, constituting a bridge or lap joint forthe rail ends so that as the wheels pass from the end of one rail to theother the click or noise is deadened and minimized. Preferably theplates 3 and 4 are extended downwardly at 7 in truss form to strengthenthe joint, such parts being adapted to lie against the rail base anddepending vertically between adjacent ties.

The bolts which pass through the fish plates 3 and 4 are shown at 8, andthe ends thereof at 9. I employ a series of springy or resilient arms 10which have parts 11 provided with an aperture 12 through which the bolt8 passes, the nut 9, in each instance, being screwed down against thepart 11. Pins or lugs 13 project from the fish plate 4 and bear againstthe parts 11, in each instance and above the spring arms 10 areremovable screw plugs 14 which bear on the spring arms and hold theirfree ends in engagement with the nuts. On taking out any plug 14, thespring arm against which it bears may be released from the nut withwhich the spring arm is engaged to thereby permit unscrewing of the nutwithout disturbing any of the other nut-s or the locking action of theremaining spring arms. The spring arms 10 are of such resiliency that onapplying a wrench of suflicient force to any nut, the arm will yield topermit the nut to be tightened without having to remove the plug 14 andthus, due to wear, the nuts may be readily tightened without having totake out the plugs 14, but when repairs become necessary, any arm 10 canbe readily swung back after removing the plug 14 which holds it.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is

In a nut lock for rail joints, the combination with rail ends, fishplates, bolts and nuts of usual construction connecting the fish plates,of springy or resilient arms through which the bolts loosely pass, saidarms having resilient parts bearing against nuts adjacent to those towhich they are secured, and independent pins on the fish plate whichengage opposite sides of the arms to hold them against swingingmovement, one of said members bearing on the spring arm, in eachinstance, and being removable to permit the arm to be swung withoutdisturbing the nuts which secure the arms.

In testimony whereof, I hereunto affix my signature in presence of twowitnesses.

CORNELIUS BEAVER.
